1. GXChain source code compilation

If you don't want to use smart contract IDE tools, or want to build a more stable and reliable compilation environment; you can compile GXChain program locally, compile, deploy, and call smart contracts through command line; GXChain source code compile, currently supports ubuntu system and mac system.

2. Create a contract using a template

Create a helloworld contract with the gxx tool

gxx -n helloworld

3. Compile the contract, generate wast and abi

Compile the contract and generate wast and wasm files

gxx -o helloworld/helloworld.wast helloworld/helloworld.cpp

Generate abi file

gxx -g helloworld/helloworld.abi helloworld/helloworld.cpp

4. Deployment contract

Need to start cli_wallet, connect local node or remote testnet node

./programs/cli_wallet/cli_wallet -swss:// --chain-id c2af30ef9340ff81fd61654295e98a1ff04b23189748f86727d0b26b40bb0ff4

Import wallet private key

# If it is a new wallet, you need to set an unlock password, here mylocalpassword

new >>> set_password mylocalpassword

# Unlock
locked >>> unlock mylocalpassword

# Import wallet private key
unlocked >>> import_key your_account_name your_private_key

# Deployment contract,0 and 0 are vm type and vm version respectively
unlocked >>> deploy_contract helloworld your_account_name 0 0 ./helloworld GXC true
